Answer: (d)

Explanation:

System of Rice Intensification (SRI)

  • SRI was first developed in Madagascar during the 1980s and has since been adopted by various countries, including India.
  • SRI offers the potential to improve rice productivity, which has been stagnant for some time, while also reducing groundwater usage by 15 to 20%.
  • Additionally, by reducing water requirements, the electricity consumption required for irrigation is also decreased.
  • SRI allows for equal or greater productivity compared to traditional rice cultivation with fewer external inputs, including less water, seed, and chemicals, which can result in significant cost savings.
